NWS National Hurricane Center Miami FL
1005 UTC Fri Mar 13 2020

Tropical Weather Discussion for the eastern Pacific Ocean from
the Equator to 32N, east of 140W. The following information is
based on satellite imagery, weather observations, radar, and
meteorological analysis.

Based on 0600 UTC surface analysis and satellite imagery through
0830 UTC.

...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...

A surface trough extends from 06N83W to 03N94W to 01N100W. The 
ITCZ continues from 01N100W to 00N103W to 03N112W to 02N130W 
beyond 04N140W. Precipitation: scattered moderate to isolated 
strong is within 130 nm NW of the surface trough between 90W and 
96W. Isolated moderate is elsewhere within 440 nm to the north 
and northwest of the surface trough and the ITCZ from 106W 
eastward. Isolated moderate also is within 400 nm to the north 
of the ITCZ from 110W westward, and within 60 nm to the south of 
the ITCZ between 111W and 118W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A middle level to upper level cyclonic circulation center is to 
the north of the Gulf of California, drifting E. Strong S to SW 
winds are in the northernmost sections of the Gulf of 
California, N of 29.5N, to the south of the middle level to 
upper level cyclonic circulation center. Upper level S to SW 
wind flow and possible rainshowers are within 320 nm on either 
side of the line that runs from 12N122W to 19N113W beyond 
26N109W. A 1011 mb low pressure center is near 29N118W. A cold 
front curves away from the 1011 mb low pressure center, to 
29N115W, and to 25N117W. The forecast is for both areas of 
cyclonic wind flow/low pressure to weaken on Friday.

To the South of the Gulf of California: tranquil conditions 
generally will prevail into the weekend, elsewhere in the 
offshore waters of Mexico.

The Gulf of Tehuantepec: It is likely for strong N winds to 
pulse during the nighttime/morning hours, starting on Saturday 
night/Sunday morning, and continuing to Sunday night/Monday 
morning. A maximum sea height of 9 feet is forecast on Monday 
morning near 15N95W.

OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND 
WITHIN 750 NM OF ECUADOR... 

Fresh NE-to-E winds will continue across the Gulf of Papagayo 
region through at least Sunday night. The wind speeds will pulse 
to strong during the nighttime hours of Friday, Saturday, and 
Sunday. Fresh winds are forecast for the Gulf of Panama during 
the same time. It is possible that the sea heights may approach 
8 feet, downstream from the Gulf of Papagayo, during the 
nighttime and morning hours, from Saturday until Wednesday.
No large swell is anticipated during the next several days.

REMAINDER OF THE AREA...

A 1011 mb low pressure center is near 29N118W. A cold front 
curves away from the 1011 mb low pressure center, to 29N115W, 
and to 25N117W. The forecast is for the 1011 mb low pressure 
center to weaken on Friday. Moderate to fresh NW winds, that are 
behind the front, will decrease in speed, from tonight into 
Friday, as the cold front weakens and dissipates gradually.

Gentle to moderate trade winds will prevail across most of the 
tropical Eastern Pacific S of 12N into the weekend, with sea 
heights generally ranging from 5 feet to 7 feet W of 115W.
